application ned June s, 1903.

To all whom it' may concern: I

Be it known that I, WILLIAM SUTTON, a citi# zen of the United States,residing at Tablerock, in the county of Pawnee and State of Nebraska, have invented new and useful Improvements in Kilns, of which the following is aspeciiica- This invention relates to kilns, the object of the invention being to provide a continuous or progressive kiln embodying a circular series or succession of burning-chambers, gas-generators, and furnaces so connected up and placedv in communication that the burning chambers or compartments may be successively charged with brick, lime, cement, or other clay products and the latter properly ltreated and removed from their respective compartments and chambers without interrupting'the opera" tion of the kiln asa whole.

A further object of the invention is to provide a special arrangement of burning chamber or compartment in connection with a suitable stack or draft-flue whereby the neces-` sary draft is obtained without the necessity of employing a high stack.

Another object of the invention is to combine with the burning chambers ory compartments a specially-arranged furnace or gasproducing generator with gas-ports located in such manner as to enable either up or down draft to be obtained.

Another object is to so arrange the furnace or coking-chamber that the same may be 'supplied with fuel either from a suitable magazine above or a door leading through the outer wall of the structure.

A further object of the present invention is to combine with the burning chambers or compartments and gas-generators a hot-air tunnel so arranged with respect to the furnace as to convey the hot air between and supply the same to one or a group of burningechambers, thus adapting the waste heat radiating from the brick already burned to be utilized'for the purpose of water-smoking or advance warming the green brick or other articles placed in the burning compartments. The arrangement referred to also enables the coke-burn'- ing magazine to be supplied with hot air, which -willassist combustion.

Serial No. 160.410. (No model.)

With the above and other objects in View the invention consists in the novel construction, combination, and arrangement of parts, as hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a horizontal section through a kiln constructed in accordance with the present invention. Fig. 2 is a central vertical section through the same, taken in line with the doorways leading to the burning-chambers. Fig. 3 is an enlarged radial section through one of the burning-chambers, showing the gas-generator, coke-burning magazine, hot-air tunnel, draftdeflecting wall, steam-vents, magazine, draftiiues, &c.

Like reference-numerals designate corresponding parts in all the figures `of the drawings.

The kiln contemplated in this invention is substantially circular in its general plan or in' the form of a Vertical cylindrical structure and comprises, essentially, outer and inner Walls, between which is arranged a circular series of burning chambers or compartments 1 to` 15, inclusive,as shown in Fig. 1. Each of said chambers or compartments is in the form ofthe segment of a circle, the compartments being divided from each other by means of temporary partitions 16, composed by preference of paper or pasteboard, whereby they may readily be destroyed either by hand or by the fire, and thus removed in order to allow the heat or products of combustion to pass from one chamber to another. The burning chambers or compartments 1 2 3, &c., are

comprised between the outer wall 17 and the p inner wall 18 of the structure, and access is had to the burning-chambers through suitable doorways 19, which extend through the outer wall 17, while between each .pair of adjoining doorways 19 are arranged one or more fuell openings 20, by means of which the fuel may be fed to the gas-generator, hereinafter described. The'outer and inner walls are con# nected by meansof a top wall 21, which is sprung over the circular series of chambers 1, 2, and 3 in the form of an arch', as shown in Figs. 2 and 3. Centrally of the structure is arranged a stack 22 of suitable size, lwhile IO encircling the stack is whatI term an inner cleaning-tunnel 23, the floor 24 of which is arranged above the bottom of the stack and also above the floor of the series of radial passages 25, which lead directly into the stack 22, as shown in Fig. 2. Any desired number of doorways controlled by suitable doors may be formed through the inner wall 18 for the purpose of allowing an attendant to pass into and out of the tunnel 23 for the purpose of cleaning the base of the stack and carrying ont the material which has accumulated therein.

Adjacent to each fuel-cleaning door and arranged below the plane thereof is a coke-burning table 26, as shown in Fig. 3, while immediately above the table is a fuel-magazine in the form of a vertical opening extending from the top or roof of the structure downward, so as to deposit the fuel directly on the table 26, which forms the burning-floor of the furnace, where the fuel is coked, the fuel also being coked as it passes over the outer edge 28 of the table and falls downward through a verticallyextending magazine 29 to the ash-pit 30 below. Extending immediately over the coking-table and running in a direction substantially radial to the stack is a gas-generating chamber 31,

Y which forms an extension of the doorway 2O and leads directly into the adjacent burningchamber. At the other side of the table is a vertical draft-passage 32, between which and the burning chamber is an interposed wall 33, which terminates above the floor 34 of the burning-chamber and also beneath the roof or upper wall of the gas-generating chamber 31. By means of suitable doors or dampers the passage 35, which forms the upper gas-port, may be thrown open and closed, and in a similar manner the passage 36, which forms the lower gasport, may 'be thrown open or closed, thus enabling a downdraft or an updraft to be produced within the burning-chamber, the draft being also regulated and controlled by means of a series of steam-vents 37, extending from the arched top of the burning-chamber upward through the top or roof ofthe structure, as shown in Fig. 3, said steam-vents being designed to be controlled by doors or dampers.

Extending in a circle around the kiln and beneath the burning-Hoor of the coking-table is a hot-air tunnel or conduit 38, which is placed in communication with each of the burning chambers or compartments 1 2 3,&e. ,by means of a passage 39, as shown in Fig. 3. In connection with the hot-air tunnel 38 a series of doors or dampers may be employed for shutting off communication between said tunnel and any of the burning-chambers 1 during the cooling operation of the brick or other products contained in the burning-chambers. A passage 40 extends from the ash-pit 3() outward, so as to enable the ashes to be removed through a suitable door controlling the outer end of said passage in a manner which will readily be understood.

Short draft-fines 41 extend beneath the inner wall18 of the kiln and afford communication between the burniiig-chambers and the stack, while the other draft-lines 42 extend from openings 43 in the floor of each burningchamber and near the outer side of the burning-chamber beneath the floor of such chamber and open out into the passages 25, which lead from the inner cleaning-tunnel 23 into the stack 22. The draft-lines 41 and 42 are designed to be controlled by suitable dampers.

In the operation of the kiln suppose that fifteen separate burning chambers or compartments are employed, the same being divided from each other by the temporary paper or pasteboard partitions 16, the opposite edges of which may be inserted in grooves in the kiln-walls or connected therewith in any convenient manner. We will assume that all of the burning-chambers with the exception ol 1 and 2 are full of burned brick or brick in the process of burning. Chamber 1 is being filled, and chamber 2 is being emptied, the brick in chambers 3, 4, 5, 6, and 7 having been burned and being now in the process of cooling and the brick in chambers 8, 9, and 1() being fired. The draft-lines leading from chambers 11, 12, 13, 14, and 15 to the stack are open, while all the other draft-lines leading to the stack are closed. All the outside doors controlling the passages 2O to the gasgenerators are closed except those leading to chambers 1, 2, and 4. Chamber 15 is then closed by two temporary partitions. Cold air is admitted to chamber 4 and drawn back through chamber 3 to the hot-air tunnel 38 to chamber 15, in which the bricks are being dried or water-smoked, and forward through chambers 5, 6, and 7, and thereby heated to a burning temperature to nourish the lires and generate gas in chambers 8, 9, 10, 11,` 12, 13, and 14, which are being fired and slowly warmed in advance. 1n this way waste heat radiating from the burned and cooling bricks is utilized to raise the temperaiaire in chambers 8, 9, and 10,which are being' lilled. \Vhen using the doors controlling the fuel-openings 20, hot air is passed under the doorways through the tunnel 38, the passage being regulated by dampers. When chamber 1 is lilled, it is inclosed between temporary partitions, and the drying, burning and cooling, emptying and filling are all advanced one chamber or compartment at a time, thus making the work practically continuous.

It will be observed that by nieans of the arrangement of tunnels and air-passages hereinabove described the necessary oxygen and hot air are supplied to the coke-burning furnace to assist in and effect a thorough combustion of the coal; also, that by being able to place the burning-chambers in comnmnication with any one or more of the remaining chambers I am able to utilize the waste heat radiating from the bricks already burned and use IOO IlO

' said heat for the purpose of water-smoking or advance warming the green bricks. By means of the detecting-wall 33 the gas may be fed to the furnace either vat a high or low point and either up or down draft obtained.u When the passage below the deecting-wall is closed, the heat and gases will enterA the burning-chamber kover the top of said defiecting-wall and pass downward and out through the draftflues 41 to the stack. If the passage at the top of the wall is closed and the bottom opened, the stack draft-flues are shut olf, and the caps or dampers of the steam-vents 37 open, an upward draft is obtained. Either the vertical magazine 27 or the fuel-door opening 2O may be used for supplying fuel to the burning floor or table 26. .When the magazine is filled `with fuel, the coking table will be necessarily partly filled, and when the draft is tuined on the heat and products of combustion 1Pwill be drawn through the coking-chamber, the gas passing into the burning-chamber,wherel it is consumed.

the burning and cooling brick be conveyed to other chambers or compartments in which the green brick has been placed, and in this way the green brick may be warmed and partially dried in advance before the products of combustion from the gas-generators and coking-tables are admitted directly thereto.

Having thus described the invention, what I claim as new is- 1. Akilii comprisinga stack, burning chambers or compartments arranged in a series around the stack and having iiue means connecting the same, draft-fines leading from the burning-chambers to-the stack, gas-generat-l ing furnaces located between the doorways, and means for directing the products of combustion into the burning-chambers either near the floor or at a point remote from the oor of the'bui'ning-chambers.

2. A kiln comprising a stack, burning-chambers arranged in a series around the stack, draft-fines leading from the burning-'chambers to the stack, gas-generating furnaces located between the doorways leading to the burningchambers, a hot-air tunnel encircling the kiln outside of the burning-chambers and communicating with the furnaces, and means for directing the products of combustion into the burning-chambers either near the floor or at a point remote from the floor of the burningchambers, substantially as described.

3. A kiln comprising av centrally-arranged stack, burning chambers or compartments arbers to the stack, doorways leading through the outer wall of the kiln to the burningchambers, gas-generating furnaces located between the doorways, and means for directing the products of combustion intothe burningchambers either near the ioor or at a point remote from the floor of the burning-chainbers, substantially as described.

4. A kiln comprising a centrally-arranged stack, burning chambers or compartments arranged in a circular series'around the stack, draft-fines connecting the bases of the burning-chambers with the stack, vent-openings leading upward and outward through the roof of the burning-chambers, doorways leading to the burning-chambers through the outerwall of the kiln, a coke-burning furnace arranged between adjacent 'doorways,a hot-air tunnel encircling'the kiln outside of the burning-chambers, a passage-way leading between the furnace and hot-air tunnel, and a'pas'sageway for conveying 4the hot air and products of combustion from the furnace into the adjacent burning-chamber, substantially as described.

5. A kiln comprising a centrally-arranged istack,burning-chambers arranged in a circular series around the stack, draft-fines connecting the burning-chambers and stack, doorways leading to the burning-chambers, furnaces arranged between adjacentdoorways, a hot-air tunnel extending around the outside of the 4burning chambers, a coke burning magazine leading from the furnace to the hotair tunnel, a fuel-magazine leading through vthe upper portion of the kiln and arranged to discharge on the burning-licor of the furnace, one or more passages for conveying the products of combustion and hot air into the adjacent bu ming-chamber, and a deflecting-wall for diverting the products of combustion prior to their entrance to the burning-chamber.

6. A kiln comprising a centrally-arranged stack,'burning chambers or compartments arranged in a circular series around .the stack, draft-fines affording communication between said burning-chambers and the stack, a hotair tunnel encircling the burning-chambers in a plane approximately on the level of the bottoms of the burning-chambers,` gasgen-V erating furnaces forsupplying gas to the burning-chambers and heat to the tunnel, and substantially horizontalv passages leading from the hot-air tunnel to the different burning chambers or compartments, substantially as described.
